hi
after 1 hour of running traditional threads I got this error :
Exception in thread thread_1:
Traceback (most recent call last):
File "/usr/lib/python3.6/threading.py", line 916, in _bootstrap_inner
self.run()
File "", line 272, in run
self.play_episode()
File "", line 246, in play_episode
a = self.choose_action(state_diff)
File "", line 287, in choose_action
return np.random.choice(np.arange(self.output_dim) + 1, p=action)
File "mtrand.pyx", line 1144, in mtrand.RandomState.choice
ValueError: probabilities contain NaN

I know this error happens because the value of "action" becomes NaN. but what should I do to solve this?
